Letters Patent No. 113,675, dated April 11, 1871.

IMPROVEMENT IN MACHINES'FOR COVERiNG CORD.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom tt may concern' Be it known that I, REUBEN LEWIS, of NewYork city, in the county and State of New York, have invented a new andimproved Apparatus for Covering Oord &c.; and do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawing formingpart of this specification.

Figure l represents a Isectional side view of my improved cordLcoveringapparatus.

Figure 2 is a transverseseotion of the same.

Similar letters of reference indicate corresponding parts.

'Ibis invention relates to certain improvements in the arrangement ofbobbins and apparatus for winding woolen or other yarn around cords orlwires to produce picture-cords, stems for artificial flowers, orsimilar covered goods.

The invention consists- First, in making ten bobbins of two longitudinalhalves, so that it can be taken from the spindle when empty; and

Secondly, in the application of a spring tension which will beautomatically regulated by the thickness of yarn on the bobbin.

A in the drawing represents the tubular spindle of a covering apparatus.

B is the bobbin, placed upon the same, filled with yarn.

The bobbin is longitudinally divided into halves, which are heldtogether by tenons a, fitting into corresponding mortises, as indicatedin g. 2.

'The cord or wire to be coveredis drawn through the tube A. The yarn forcovering it is gradually unwound from the bobbin and placed around thecord or wire, which is fed ahead.

In the machines heretofore in use the cord had to be cut whenever theyarn had all been taken from one bobbin, as otherwise the empty bobbincould not be removed nor a filled one put in its place.

By the use of the sectional bobbin I can continue the operation on onecord 0r wire for an indenate length. I draw the cord from the tube Athrough as many bobbins filled with yarn as I desire to use on the samecord, besides having one filledbobbinon the tube. When this latterbobbin is empty I `take it to pieces and remove it thereby from thetube, and slip another filled bobbin from the cord upon the tube,continuing thus to operate on the same cord without cutting it.

Tension on the bobbin is provided by means of a string, b, which is withone end hooked to an eye, c, at the end of the spindle, then drawnthrough an eye, d, at one of the projecting arms e e of the saidspindle, then laid over the filled bobbin and finally hooked to a Wireor other spring, f, which is attached to the` other arm e.

Small tubes g g are slipped upon the string b to preventits cutting theyarn. It will be noticed that the spring f will be strained the mostwhen the bobhin is filled, and that its tension will relax in the samedegree as the bobbin becomes smaller.

The tension is thus automatically regulated in the desired manner, andthe troublesome manual adjustment of weight-s hitherto employeddispensed with.

Having thus described my invention, 4

I claim as new and desire to secure by Letters Patent- 1. The bobbin B,made of two longitudinal halves so that it can be removed from tbespindle when empty, without requiri'ngthe cutting of the cord, asspeciiied.

2. The tension-string b, spring f, and frame e, when combined asdescribed wit-l1 the divided bobbin B, ar-

ranged on the spindle A, as and for the purpose spec-V` iied.
